PURPOSE:To collect the plant data of a fault mode in a short cycle and those of a normal mode in a long cycle respectively through simple constitution, by providing a high-speed data area and a low-speed data area within a memory when various types of plant data are collected for a fixed period. CONSTITUTION:An operator operates a console, etc. not shown in the figure to collect and reproduce the plant data in a long cycle and for a long period. In such a case, a low-speed record starting request (b) is supplied to a low-speed input means 4. Then the means 4 reads successively each digitized plant data (c) out of an analog input part 1 in a low-speed recording cycle stored in a low- speed recording cycle memory part 4A. While the operator operates the corresponding console to collect and reproduce the plant faults in a short cycle. Thus a high-speed record starting request (j) is delivered to a high-speed input means 8. Then the means 8 reads successively the plant data (k) out of the part 1 in a high-speed recording cycle stored in a high-speed recording cycle memory part 8A in response to the request (j). |
